Petrolatum

Commonly feared, low concern·Strong evidence

A time-tested occlusive that seals in moisture and helps damaged skin heal, widely used in dermatology for wound care. Cosmetic-grade petrolatum must meet purity standards that remove the polycyclic aromatic hydrocarbons found in crude sources, and it is considered one of the most effective and well-studied barrier ingredients available.

The myth vs the evidence

Myth: petrolatum is "toxic" petroleum that suffocates skin or causes cancer. Evidence: fully refined, cosmetic and USP-grade petrolatum is purified to remove the impurities of concern, and the EU permits its cosmetic use subject to that refinement documentation. Dermatologists commonly recommend it for eczema, dry skin, and post-procedure healing.

Questions

Is petrolatum really just toxic petroleum jelly?
Cosmetic-grade petrolatum is highly refined to remove impurities found in crude oil and must meet purity standards under EU and US regulations. It is not classified as a carcinogen and dermatologists commonly recommend it for eczema, wound care, and post-procedure healing.
Does petrolatum suffocate skin or clog pores?
Petrolatum works as an occlusive to seal in moisture and help damaged skin heal. The published evidence does not support the concern that it prevents skin from functioning normally; this fear appears to stem from confusion about its industrial origins rather than actual mechanism of harm.
